Thread: 3G Help

I Recently Bought A HTC Tattoo ( Xmas Present ) And Have Used The Text And Web Sim Card.
When I Activated The Card My Texts Came Through Just Fine However My 3G Didn't And Still Doesn't Work, O2 Have Told Me To Enter My GPRS\MMS Settings Manually However They Are Already There And I Can Still Not Receive The MMS Message With The 3G Settings.

Any Advice?
